ABSTRACT:
A device for removing a hub and a bearing from a spindle of an automotive wheel drive, and also for pressing a bearing and a hub back into the spindle. The device includes a screw drive which is rotatable but does not move longitudinally when pulling the hub out from the bearing or pushing the bearing out from the spindle. A housing is secured to the hub and threadedly attached to the screw drive. The housing moves inward along the screw drive for pulling the hub out from the bearing, as the screw drive is rotated. A nut is threadedly attached to the screw drive and moves inward along the screw drive for pushing the bearing out from the spindle, as the screw drive is rotated. The rotatable screw drive is also utilized to move longitudinally toward the spindle for pressing the bearing back into the spindle and pressing the hub back into the bearing.
